SciMath Keyboard

Scientific and mathematical symbols for iOS and iPadOS

What Is SciMath?

SciMath is a keyboard for iOS and iPadOS that gives you the symbols science, mathematics, and technical writing actually need — without copying from character maps, switching apps, or approximating.

Every symbol is a proper Unicode character. It copies, searches, and renders correctly in every app that supports Unicode text.

SciMath is a one-time purchase. There is no subscription, no in-app purchase, and no advertising of any kind.
